This is fairly normal. There is a huge dynamic that goes on with any new "love", which in the case of an A, can add even more.
Of course, what you've heard is either third party or from someone who wants to only tell you what he thinks you want to hear. Still, from what you have heard, this A sounds doomed to fail.
So take a moment and let yourself understand that "it ain't over, 'til it's over".
He can only get the D he SAYS he wants (believe none of what they say and only 50% of what they do) as fast as he can financially afford it.
Understand that even if you are OK with D happening, this is his baby. Let him do what he needs to do.
